When downgrading from Windows 11 back to Windows 10 (within the 10-day period), will my system stay joined to the on-prem domain?

Question

A have a remote system that was upgraded from Windows 10 to Windows 11, but has not yet been approved for our environment. For compliance, we have to downgrade this system back to Windows 10 and is still within the 10-day period. Since we use on-prem domain join, will this have any impact on the system once we revert back?

Answer 1

When you perform a downgrade all settings, personalization , etc. will remains and in such a case, the system stays in the domain and will keep all policies applied to the device. However, if you setup a policy which only works on Windows 11, it won't work on Windows 10. In case, you setup policies for the Windows 11 group, then when it detects it is Windows 10, those policies won't apply. However, in normal conditions all policies should work and the device should stay in domain. However, it is recommended to test it once to make sure everything working as expected.
